AND FASTENER THEREFOR.

SPECIFICATION forming part of Letters Patent No. 613,493, dated November 1, 1898.

Application filed June 4, 1898- Serial No. 682,523. (No model.)

T0 at whom it may concern:

Be it known that we, MARTIN CAVANAUGH and CHARLES H. HESS, citizens of the United States, residing at Zan es'ville, in the county of Muskingum, State of Ohio, have invented certain new and useful Improvements in Jars and Fasteners, of which the following is a description, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Our invention relates to improvements in jar-closures, our object being to provide a structure cheaply made, easily applied, and efficient in operation.

Primarily the invention contemplates a clamp of the Y-shaped type, constructed in a novel manner, and, secondly, a cap of special structure for use in connection with such Y-shaped clamps.

The invention consists in the various matters hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a sectional elevation of a portion of a jar embodying the present invention; Fig. 2, a top plan view of the jar and cap, the clamp being absent. Fig. 3 is a detail perspective of the clamp, and Fig. 4 is a perspective showing the clamp applied. v

Referring now more particularly to the drawings, A represents the body' of a jar,

. which is provided with a flange B on the interior of the neck and with a bead O extending around the outer periphery of the neck.

D represents the cap, which is provided with a peripheral flange E, fitting closely within the neck of the jar and adapted to rest on the shoulder B, a suitable gasket a being interposed between the shoulder and the flange.

The clamp is indicated by the letter F, and is constructed of a suitable piece of sheet metal, spring steel being preferably employed. The clamp is in the form of the letter Y, having the arm 0 and the diverging arms I), the outer end of each of these arms being bent downwardly and outwardly to form hooks adapted to engage the bead. The hook portion upon the arm 0 is slightly extended and turned outwardly to form a fingerpiece (1. Preferably the metal is made thinner at the meeting-point of the three arms for a purpose to be more fully hereinafter described.

In applying the clamp, the cap having been properly placed in the jar, the arms I) are separated more than normally, the hook ends being engaged with the bead, and the hook upon the arm a is then forced over the bead upon the side of the jar opposite that engaged by the hooks of the arms b. This causes the material of which the clamp is formed to tend to form a straight line between the extreme points of the arms, and as a result the metal is depressed at the point e, thus forcibly bearing downwardly upon the cap and firmly holding the same in position. The material be ing thinned at this point e, the depression of said point is facilitated.

In order to retain the arms 19 in their abnormally-distended positions and also to guard against displacement of the clamp upon the cap, said cap D is provided in its upper surface with a Y-shaped groove g, in which the clamp rests when in engaging position.

From the foregoing it will be apparent that the present closure is made at very little expense and with very little labor, but that when the parts are applied the cap is firmly held in position. Furthermore, the parts can be used repeatedly without injury.

Having thus described our invention, what we claim as new, and desire to secure byLetters Patent, is

1. A clamp of the nature indicated, comprising a relatively narrow integral plate of resilient material having three arms, and engaging members upon said arms,whereby two of the arms may be abnormally separated; substantially as described.

2. A clamp of the nature indicated, com prising an integral plate of resilient material having three arms, said plate being thinned at the point of juncture of the arms, and engaging members upon said arms; substantially as described.

3. The combination with a receptacle, of a cover therefor, a clamp comprising an integral plate of resilient material having three arms, two of said arms being abnormally separated whereby said clamp assumes a Y shape, members securing the arms to the re ceptac1e,and means for holding the two abovementioned arms in their abnormallyseparated position; substantially as described.

4. The combination with a receptacle, of a cover therefor, a clamp comprising an integral plate of resilient material having three arms, two of said arms being abnormally separated whereby said clamp assumes a Y shape, members securing the arms to the re- 10 ceptacle, and a portion upon the cap between the two above-mentioned arms and holding them in their abnormally-separated position; substantially as described.

In testimony whereof We afiix our signatures in presence of two witnesses.
